Answer:
Those who sacrifice for others are great people.
Step-by-step explanation:
This question refers to the following paragraph from The Gift of the Magi, a story written by O. Henry:
And here I have lamely related to you the uneventful chronicle of two foolish children in a flat who most unwisely sacrificed for each other the greatest treasures of their house. But in a last word to the wise of these days let it be said that of all who give gifts these two were the wisest.
This story tells about Della and Jim, a young and poor married couple. On Christmas Eve, they buy each other gifts despite having very little money. Della sells her hair to buy a platinum pocket watch chain for Jim, and Jim sells his pocket watch to buy a set of ornamental combs for Della. Despite receiving gifts they cannot use, Jim and Della realize how much they are willing to sacrifice for each other and how priceless their love really is.
This is what the given paragraph tells us - that those who sacrifice for each other are great people. It doesn't matter that they don't have much money - Jim and Della love each other and that's all that matters. There is nothing foolish about that.
